JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 773,935, dated November1, 1904.

. Application filed May 16, 1904:.

To all whom it may concern:

Be it known that I, FRANK WILLIAM HAL- LOOK, ofDerby,in the countyof NewHaven and State of Connecticut, have invented a new and usefulImprovement in Journal-Bearings; and I do hereby declare the following,when taken in connection with the accompanying drawings and the numeralsof reference marked thereon, to be a full, clear, and exact descriptionof the same, and which said drawings constitute part of thisspecification, and represent, in

Figure 1, a vertical sectional view of a journal-bearing constructed inaccordance with my invention; Fig. 2, a sectional view on the line ([6of Fig. 1; Fig. 3, a top or plan View of the lower box.

This invention relates to an improvement in journal-bearings, andparticularly to that class which are provided with channels or groovesin their bearing-surfaces, which channels or grooves contain lubricatingmaterial, the object of this invention being a simple construction inwhich the bearing will be lubricated throughout substantially its entirelength and one in which the lubricating material will be freelysupplied; and the invention consists in certain details of constructionand combination of parts, as will be hereinafter described, and recitedin the claims.

In carryingout my invention Iemploy two semicircular boxes 2 3 ofsubstantially usual form provided with the usual journal-bearing linings4c and 5, and in the lininge I form two or more spiral grooves 6 7 andin the lining 5 corresponding grooves 8 and 9, the grooves in therespective linings being so arranged that when the boxes are placed to-'gether to form the journal-bearing the ends of the grooves 6 and 7 willnot register with the grooves 8 and 9, but be, as it might be said,staggered, so that the edges of the linings et and 5 form stops at theends of the grooves 6, 7, 8, and 9, as clearly shown in Fig. 1. In thebox 2 are oil passages or holes 10 and 11, registering with the grooves6 and 7, and in the bottom of the box 3 and lining 5 are slots 12 and13, the purpose of which will hereinafter appear. This bearing isparticularly adapted to be used with a hanger 14, so con- Serial No.208,082- (No model.)

structed and arrangedthat a chamber 15 will be formed between the box 3and the inner face of the hanger 14. In the grooves 6 and 7 I placestrips 16 of wicking, felt, or other suitable lubricating-conductingmaterial, the strips corresponding in length to the length of thegrooves, and these strips of wicking pass over the holes 10 and 11,through which lubricating material is admitted. In the grooves 8 and 9strips 17 of wicking, felt, or other suitable lubricating-conductingmaterial are placed, and these strips of wicking are of such a lengththat their central portions 18 may be passed through the slots 12 and 13and be doubled on each side thereof in the chamber 15, which is intendedto contain a supply of oil. While I prefer to form the strips 17 in asingle piece, two pieces might be employed. By keeping the chamber 15supplied with oil and feeding oil through the holes 10 and 11 to thewicks 16 the strips in both linings are kept lubricated, and theseseveral strips substantially cover the entire length of the hearing, sothat the journal is lubricated throughout its bearing-surface. Owing tothe fact that the ends of the strips abut against the edges of thelinings, they are not liable to become displaced and yet may beconveniently removed and replaced when required.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A journal-bearing comprising a two-part box and linings therein,there being spiral grooves in said linings, said grooves so disposedthat the ends of the grooves in one part abut against the adjacentungrooved edges of the other part, a lubricant-conducting material insaid grooves. 2. A journal-bearing comprising an upper and a lower boxand linings therefor, there being spiral grooves in said linings, saidgrooves so disposed that the ends of the grooves in one part abutagainst the adjacent ungrooved edges of the other part, and slots in thebottom of the grooves of the lower box, and lubricant-conductingmaterial in said grooves said conducting material extending through saidslots, substantially as described.

3. A journal-bearing comprising an upper l box, and'strips oflubricant-conducting mateand a lower box and linings therefor, therebeing spiral grooves 1n said llnings, said grooves so disposed that theends of the grooves in i one part abut against the adjacent ungroovededges of the other part, slots in the grooves of the lower box openingthrough the box combined With a hanger in which said lower box rests,there being a chamber between the in- I O ner face of the hanger and theouter face of said rial in said grooves and extending through saidslots, substantially as described.

in testimony whereof I have signed this specification in the presence oftWo subscrib- 5 ing Witnesses.
